Post Parotidectomy Quality of Life in Patients with Benign Parotid Neoplasm: A Prospective Study.

Parotid tumours are not uncommon. The management is surgical for benign and malignant parotid neoplasm. Due to the location of parotid gland and its intricate relationship with facial nerve, cosmetic and functional outcomes after parotid surgery are extremely important. Objectives of the study were to analyse facial nerve functions with emphasis on the quality of life of patients undergoing surgery for parotid neoplasm. A prospective study was conducted on patients presented with parotid neoplasm and undergone parotid surgery. Patient with malignant neoplasm were excluded. 30 patients with benign parotid neoplasm in final histopathology were included in the study. Post operative assessment of facial nerve was done using postparotidectomy facial nerve grading system. Symptom-specific QOL was assessed with the parotidectomy outcome inventory-8. Aesthetic outcome was evaluated with an ordinal scale. Posterior belly of digastric muscle and tragal pointer were the commonest landmark used for facial nerve identification. Temporary facial nerve dysfunction was present in six (20%) patients with marginal mandibular branch most commonly involved. 96% of the female patients and 91% of the male patients rated the cosmetic result as good or very good. A statistically significant difference is noted between superficial parotidectomy and total Parotidectomy for cosmetic outcome and sensory impairment. We noted that changed appearance due to resection of the parotid gland and scar and sensory impairment in the area affect the quality of life of patients and such affect are more after total conservative parotidectomy.

Post-operative Sensorineural Hearing Loss After Middle Ear Surgery.

Chronic suppurative otitis media is managed by tympanomastoid surgery often requires mastoid drilling. Sometimes patients develop sensorineural hearing loss after middle ear surgery. Objective of the study was to compare pre and post operative bone conduction thresholds after middle ear surgeries. The study was conducted on 90 patients who had undergone middle ear surgeries, 30 patients of tympanoplasty (group I), modified intact canal wall mastoidectomy and tympanoplasty type-I (group II) and modified radical mastoidectomy (group III) each ware included. Demographic and clinical data were reviewed. Duration of surgery, ossicular and middle ear status and drilling time noted. Pre operative and post operative (after 3-4 months) bone conduction thresholds were compared statistically. A value of p < 0.05 was considered statistical significant. The average pre-operative hearing loss of study group was 43.78 ± 14.22 dB. Though postoperatively mean air conduction threshold improved to 36.07 ± 13.05 dB, six patients presented with deterioration of hearing. Mastoidectomy has been performed in all six. Post-operative worsening of bone conduction was seen in three patients (13.75-21.5 dB), one patient of group II and two patients of group III developed postoperative worsening of bone conduction thresholds. Significant hearing losses may occur after tympanomastoid surgery in few patients. While we are evaluating the results besides reporting average results such individual patient should be identified.
